I mounted my leupold on my 300 with a Picatinny Rail and burris rings and had to lap the crap out of it because the the rear was a little higher then the front. Well after I finished lapping the rear ring had zero black left so the ring was smooth as all get out.. now after talking to a couple people they are saying that the scope is prone to move.. also I didn't lap it so much that that the edges of the rings touched where the screws are.. there is still a gap between the top and bottom even after being screwed down if that makes sense.. so yall think I lapped to much or am I just being paranoid? I was gonna take it to a gunsmith but every time I've seem people do this they don't check to see of the rings are even and the cross hairs are always tilted..

Maybe you can educate me, but I've never understood this opinion. If your mounts are so far misaligned that you need to lap them, then why would better quality rings fix that? I don't believe the misalignment that lapping is intended to fix is in the rings themselves.

I didn't lap the Burris rings on my new Savage I bought awhile back and they're working fine.

I've mounted several lately ad each was almost perfectly aligned before I lapped them. I would be concerned if they were that far off initially. However, if you torqued them and there is space then I agree that you are okay. Start shooting!

That doesn't hurt the barrel? I was building pvc with a fan and ice pack.. lol

The barrel would have to be hotter than you can get it by shooting for it to hurt it. I havn't seen the towel method hurt a barrel yet. Thin barrels heat quickly and cool quickly. Same as thick barrel heat slowly and cool slowly.

One of the best machine guns the world has seen was water cooled. The downside to it was that the squad had to carry water for the reservior or urinate in it once they got to where they were going.
